What should you pay attention to when using combat bullets in STALKER 2: Heart of Chernobyl
You may pick up tons of ammo while exploring, but there's never enough ammo in this game. You will mainly face two types of enemies: humans and mutated creatures. Humans have less health and can be defeated with a single headshot in most cases; mutated creatures are another story entirely.
In "Stalker 2: Heart of Chernobyl", mutated creatures may appear in small groups with low health, or as individual monsters with high health. Either way, they require a lot of ammo to defeat, and you can't let them run out because it's nearly impossible to defeat them with just a knife. Therefore, conserving ammunition is crucial.
Mutated mobs usually do not drop any loot, so they are mainly ammo consumers.
When fighting human enemies, you can save ammo by aiming for the head whenever possible. Remember, if you hit an enemy's body, you'll consume more ammo.
